Abstract

PURPOSE: To make it possible to perform the operation very easily and also exactly, by providing a thyristor, a control circuit, a self-holding means and a time limit device.
CONSTITUTION: When connected to the electric power source 1, SCR3 conducts by a signal from the control circuit 4, the heating element 2 is electrified, it rises up to a set temperature by the temperature controlling variable resistor 5, and SCR3 keeps the temperature constant by repeating on and off by said temperature. At the beginning of electrification, once the push-on switch 11 is turned on, the time limit device 8 and the self-holding means A for LED23 start the operation, and the time limit device 8 generates an output signal. And the transistor 6 is turned on. As a result, the variable resistor is short-circuited, and temperature of the heating element rises from the room temperature up to the maximum temperature, by which the temperature is maintained. When the period in which said output signal is provided has passed, the transistor 6 is turned off. The push-on switches 10, 9 also perform the same operation.
